The widespread usage of electricity promoted to defend the development of thunder product and be a high pressure power grid to provide motive and illuminate for the thousand 10000, thunder and lightning also a great deal of bane high pressure lose to change to give or get an electric shock an equipments.The high pressure line installs Gao, be apart from long, cross geography complications, is strike by lightning easily medium.The protection scope shortage of the lightning rod with protect up to thousand power lines, so avoid thunder line as to protect high pressure line of new connect a Shan machine to emerge with the tide of the times.After the high pressure line acquire a protection, the hair linked with high pressure line, go together with electricity equipments to be still conduct electricity to press damage, people discover this is because"respond thunder" is play tricks.(Respond the thunder is to respond the metals conductor of neighborhood because of keeping shot thunder to turn on electricity in, respond the thunder can pass 2 kinds to differently respond way incursion conductor, one is an electrostatic induction:When the electric charge in thunder cloud accumulates to ga

當(dāng)人們知道,雷電是一種電力的現(xiàn)象后,向崇拜的雷電與恐懼感逐漸消失,并開始與品味,科學(xué)來自新觀察自然現(xiàn)象,這魔術(shù),希望使使用或控制雷電活動,以造福人類.超過二百年以來幾乎富蘭克林為首的小康就技術(shù)開始挑戰(zhàn)對雷電,他發(fā)明的避雷針可能被視為向在最早現(xiàn)階段維護(hù)雷聲大的產(chǎn)品和產(chǎn)品名稱,今天這幾乎由全體人民已知道.事實上,富蘭克林發(fā)明避雷針是認(rèn)為金屬避雷針的角度談?wù)剬﹄娏Φ墓δ?,可合成電荷在積雨云,使積雨云和電場的地球一樣低的水平,不能突破的空氣中,避免罷工,因此,閃電發(fā)生時,當(dāng)時的避雷針,必須要求尖利.但是事后研究闡述證明:閃電控制棒是發(fā)生不可避免的打雷的,因為它可以證明雷聲大,是因為建筑物較高,是矗立在簽署的避雷針改變了大氣電場,使積雨云的一定范圍內(nèi)始終把對電力對閃電棒,也就是說,避雷針只是比它周圍其他物體更容易連接山雷電,避雷針是罷工的閃電,但是它可以對其他物體加以保護(hù),這是捍衛(wèi)建筑物的一種方式,避雷針防雷更加深刻的研究表示,連接避雷針山的功能,幾乎有一些建筑物不是很高,但沒有形狀,可說是避雷針不一定是雷聲大,技術(shù)的境界,將會知道一起像現(xiàn)在這種類型的防雷裝置。廣泛使用的電力,促進(jìn)了發(fā)展防雷產(chǎn)品和一個高壓電網(wǎng)提供的可以照亮千萬人類電動機,雷電也是大的高的壓力禍根,失去了改革,就相當(dāng)于給予或得到一個電動休克.
一、建筑物的防雷分類
對規(guī)范中明確指出的防雷建筑物類別,可直接套用。規(guī)范中對有些建筑物僅指出大于預(yù)計雷擊次數(shù)XX次/每年,而歸屬二類或三類防雷建筑物。對于這些規(guī)定,在設(shè)計中僅憑直觀感覺和經(jīng)驗,就不能明確確定其建筑物所屬防雷類別,使應(yīng)做二類防雷誤做成三類,應(yīng)做三類防雷而沒做,結(jié)果是對建成的建筑物造成一定的隱患。這就有必要據(jù)當(dāng)?shù)氐哪昶骄妆┤占敖ㄖ锼诘氐牡乩?、地質(zhì)土壤、
